You will always have that fear in your head about it all. You can't worry about pleasing everyone else either, if you want a baby and so does your dh then do it. You can't wait for the perfect time, because it will never come. When you do have a baby all the pain and worries will dissappear and all you will see is a beautiful child! Try not to stress out about it, God will provide when the time is right. I know it's difficult to have a husband in the service, but I also know that he would do everything in his power to be there with you through it all. G'luck to you and you will be in my prayers.
Agree wholeheartedly with babydreams9! Every single pregnant woman has the SAME fears you have!!! It's just one of those things you have to jump into and when you DO become pregnant, it is the MOST AMAZING thing you'll ever experience. All the negative stuff is NOTHING compared to the baby kicks and hiccups, getting to name them, hold them, nurture them... It's worth it!
There will never be a "perfect" time to have a baby... if you wait for that, it'll never happen! The only time you should hold off is if your heart is telling you too. You have to listen to your gut instinct and follow it... and understand that worries are normal. And they only increase in number and intensity once you know you have a little one growing inside you! If you feel mentally ready for the journey, you and your husband are on the same page (talk about it - a LOT - everything - including how you want to raise your kids), and your heart tells you to go for it.... then go for it. Whatever decision you make, it'll be the right one. Best wishes to you!
